1988: Summer Wing Ponies
LITTLE FLITTER
Yellow "winger" with pale pink mane and tail, dark pink hummingbird symbol, pink, blue and yellow butterfly wings
Little Flitter is meant to have pale pink hair, though mine is more than a little bit faded out (sorry for that!) I have a fleeting memory of her being quite a sweet character in the comic, though honestly my recollection is a bit hazy, which means I don't think she made a lasting impression on me!
An odd fact about Little Flitter is that one of the playset Petite Ponies was named after her!
